A Study on Conformal Heating of Curved Mold Using CNT Film Heater [PDF]

한국정밀공학회지, 2022
Injection molding is one of most widely-used polymer processing technologies in which hot polymer fills a mold cavity, and is solidified during the subsequent cooling process. In the mold filling stage, the mold temperature should be high to improve flow
